Promix hp# help

Greetings rollitupers! Tomorrow I plan on transplanting 30 clones into 6x6 pots for a SOG. I plan on using a bail of "promix HP" with some "just right xtra" cut into it and a good deal of perlite. Do you recommend that I use dolomite lime as a buffer? I plan on using "pure blend pro soil flower" as I'm only going to veg for a few days and switch to my unorthodox circadian rhythm light schedule. I'll only use flowering nutes. Also I use RO. Let me know what y'all think.

I mix 50-60% Pro-Mix HP with 20-25% Kellogg Patio Plus and 20-25% Perlite. I add 1.5-2 tbsp/gal powdered dolomite to that.

I don't know anything about the other stuff you mentioned.

Bump bump bump

I appreciate the insight. On a side note, does anyone know how to start the sog with clones? Should I amend anything into the soil except for botanicares PBP bloom and lime? I'm begging for only a few days before my lights flip to flower.
